Featuring Shimano’s innovative Shadow clutch technology, the Deore XT rear derailleur is designed for today’s aggressive style of trail and all-mountain riding. By maintaining chain tension, the Shadow system eliminates chain slap and lowers the chances of dropping your chain. Other improvements include reduced noise and rotational drag as well as a low-profile pulley cage for better clearance over harsh terrain. Why choose an XT derailleur over a cheaper derailleur? Built for heavy duty and long life in demanding trail conditions, the XT's overall linkage is stiffer and has a more machined construction, increasing durability and stiffness, which also increases shift quality. The pulleys are also of a higher quality, and spin easier for less drivetrain drag. The whole derailleur is built to exacting standards and will last significantly longer than a cheaper derailleur as well.

Don't know which cage length to choose? Choose a long cage "SGS" derailleur if you have 3 chainrings on your crankset, and a medium cage "GS" if you have 2 or fewer front chainrings.

When I switched to the clutch on my Trek Remedy I did not have high expectations. I was running a tripple up front and was constantly dropping a chain. I fully expected I would need a guide soon and though the clutch might quiet things down a bit. I totally underestimated the product as it not only silenced all chain slap but also prevented chain drop. I have no need to use a guide now and I will never run a MTB of any kind without a clutch derailleur. Further, I won't run a cross race without one either. This is a fantastic design that held up for me over several hundred miles.

Installed to replace a non clutch XT mech (stick ripped apart the direct mount hanger), works well out of the box and shifts well. Unfortunately though, it seems to be made out of cheese and could not survive a small knock which bent it to the point I cannot get lowest gear.

Just simply not worth the money when you are paying for light weight materials that cannot take any knocks, it is mountain biking after all.

I bought this derailleur to set a mountain bike up as a 1x10 with a narrow wide chainring and so far have been very pleased with the results! I have taken the bike on several rides, and have really enjoyed improved shifting performance and have yet to experience a chain drop (knock on wood). If you're looking at this product, you probably know that XT is one of the industry standards in balancing quality, performance, and durability; this derailleur is no exception!

XT line is as good as it gets short of the slight weight savings with XTR. This was part of a 3x9 to 3x10 upgrade to my urban warrior (Giant Trance MTB adapted for hostile pavement) - that's why I rated mountain components good for road use - lots of roadies eat my dust. Lockout tension completely eliminates chain looseness. Teamed with KMC DLC chain, XT shifters, and XTR cassette pulls smoothly and shifts are crisp and immediate - very nice!

Converted from 3x10 to 1x10 and switched to clutch medium cage RD. Rode the bike pre clutch for several weeks with a few chain drops. So far with Shadow Plus clutch no drops. This RD is truly as smooth and quiet as the other reviews claim. Very nice added benefit.

After a stick ate my last non-clutch derailleur, I bought this one. I'm pretty used to shifting in big-big on the downhills to avoid chain slap. With the clutch, I don't have to do that anymore. Nice and quiet.

I've never had any issues with Shimano's XT derailleurs - they just take a licking and keep on shifting. I recently switched to a OneUp 1x10 setup (42t big cog) so bought the medium cage derailleur and replaced the outer cage plate with OneUp's RAD cage plate - that made shifting work extremely well even with the wider range gearing (11-42).

Has worked fantastic with a 1x10 setup without a chain guide. I paired this derailleur with a XT 11-36 cassette and a race face narrow wide 30T single ring. It has worked great, no chain drop and very quiet riding.
